: * * *: 6 6.6.2 DRYSTONE MASONRY STRUCTURES<br />

Description<br />

Structure made of a drystone masonry<br />

shell, normally round, and with a conical<br />

roof made of trees and plants.<br />

Uses<br />

Dwelling designed to provide temporary<br />

shelter for charcoal workers wh<strong>en</strong><br />

they were making charcoal.<br />

Site<br />

In a evergre<strong>en</strong> oak wood.<br />

Ground Plan<br />

Circular, 2.90 m in diameter inside.<br />

Roofing<br />

Conical and made of trees and plants.<br />

It was built using evergre<strong>en</strong> oak<br />

trunks, some acting as master beams<br />

and the rest laid betwe<strong>en</strong> them.<br />

Reeds were th<strong>en</strong> placed on top until a<br />

waterproof covering was obtained.<br />

Facings<br />

60 cm wide and quite low (1.20 m)<br />

double facing made of undressed<br />

stone.<br />

<strong>Materials</strong><br />

Limestone for the facings and evergre<strong>en</strong><br />

oak trunks and reeds for the<br />

roof.<br />

Flooring<br />

Earth.<br />

Op<strong>en</strong>ings<br />

The only op<strong>en</strong>ing is a small, 40 cm<br />

wide door with only its jambs made of<br />

stone.<br />

Accessory items<br />

Accessory features outside the hut<br />

are a dry stone bread ov<strong>en</strong> plus a<br />

mosquera, or shady spot, made of<br />

pine where the charcoal worker<br />

rested and ate (Calviflo, 1999). As for<br />

charcoal manufacturing structures,<br />

near the hut there is always the charcoal<br />

bunker and quite oft<strong>en</strong> a loading<br />

place where animals would be loaded<br />

with the charcoal.<br />

The bread ov<strong>en</strong> is round and has a<br />

very simple vaulted roof made of stones<br />

laid on <strong>en</strong>d. The only hole is the<br />

op<strong>en</strong>ing which in this case is square<br />

and made of 4 pieces of stone. It is<br />

<strong>en</strong>tirely constructed with barely dressed<br />

limestone with the most dressed<br />

stone forming the op<strong>en</strong>ing.<br />

The charcoal bunker is the round,<br />

paved area of land measuring 7.75 m<br />

in diameter where the charcoal pile<br />

was built. It is made of a course of larger<br />

stones (some 35 cm high) which<br />

form its edge. The space inside is full<br />

of large stones with rubble and very<br />

dry and clayey red earth on top. The<br />

gaps betwe<strong>en</strong> the stones served as<br />

ducts through which a small amount<br />

of air flowed which was suffici<strong>en</strong>t to<br />

fire but not burn the charcoal.<br />

A conical pile or heap of bits of wood<br />

(the sitja) was placed on the charcoal<br />

bunker and covered with earth. The<br />

wood was set on fire and it slowly<br />

burnt to produce charcoal.<br />

Location<br />
